Obama approval: 52/47
Head-to-head: 49/45
"A president’s job approval rating is one of the best indicators for assessing his chances of reelection. Typically, the president’s job approval rating on Election Day will be close to the share of the vote he receives. Currently, 52% of voters say they at least somewhat approve of the president's job performance. That’s his highest approval rating in more than a year-and-a-half, since January 2011."
